Key Features of BM5-B Series Hydraulic Motors
-
Upgraded end face distribution design, based on the BM5 series, with enhanced automatic wear compensation function, ensuring smoother operation at low speed, effectively reducing internal hydraulic loss and improving operation stability and volumetric efficiency (up to 85%-92%).
-
Reinforced double-row tapered roller bearings on the output shaft, adopting high-strength materials and precision machining, which can bear larger static and dynamic radial loads than the BM5 series, significantly enhancing the load-bearing capacity and service life of the motor.
-
Dual-seal structure optimization, combining high-temperature resistant oil seal and dust-proof seal, with stronger sealing performance, capable of withstanding higher back pressure, and suitable for harsh working environments such as high temperature, dust, humidity and heavy load.
-
Excellent low-pressure start performance and larger starting torque than the BM5 series, which can realize stable start and continuous operation under low oil pressure conditions, perfectly adapting to the needs of heavy-duty start scenarios in mining and construction industries.
-
Flexible structural design, compatible with the mounting flanges, output shafts and oil port types of the BM5 series, supporting customized design according to different working mechanisms and installation requirements, and easy to replace and maintain.
-
Higher torque density and more reliable performance, with strong environmental adaptability, interchangeable with mainstream heavy-duty hydraulic motor models, widely used in low-speed and heavy-duty working scenarios, and energy-saving effect is more prominent than the previous generation.
Performance Characteristics
Application Areas
-
Agricultural machinery: Large combine harvesters, heavy-duty rotary tillers, high-power feed mixers and large-scale agricultural irrigation equipment.
-
Construction machinery: Hydraulic excavator travel and slewing drives, large rollers, heavy-duty cement mixers and heavy lifting machinery, adapting to the harsh working conditions of construction sites.
-
Industrial equipment: Large conveyors, high-load winding machines, injection molding machine preplasticizing screw drives and high-pressure vulcanizing machines.
-
Mining machinery: Coal shearers, roadheaders and mine hoists, with strong adaptability to harsh mining working environments such as dust and high load.
-
Marine equipment: Ship anchor winches, large fishing boat net hauling equipment and ship steering systems, with excellent corrosion resistance and waterproof performance.
